Title: Treatment of electroconductive films
Inventor: TARNOPOL MILTON SIDNEY
IPC: C03C17/25
Filed: 1951-05-08
Abstract: 724,088. Electric heating resistance coatings. PITTSBURGH PLATE GLASS CO. May 8,1951, No. 10838/51: Class 39 (3) [Also in Groups XXIII and XXXVI] An electro-conductive tin-containing film or coating on a glass or other refractory base is removed wholly or in selected areas or decreased in thickness according to treatment which includes applying to the film to be removed a non-oxidizing acid and a metal more electro-negative than tin. The term tin-containing means a product which contains tin whether such tin be in elemental or metallic form or in the form of an oxide or other compound. Examples of non-oxidizing acids used are hydrochloric, hydrobromic, sulphuric, phosphorous, sulphurous and trichloroacetic acids. Examples of metals more electronegative than tin are zinc, cadmium, aluminium and iron. Several embodiments and details as to tin oxide deposition processes are described. According to one example, powdered zinc is sprinkled over a tin oxide-coated glass base or sheet and then the chosen aqueous acid is applied and finally the desired removal is effected by washing the decomposed coatings off the glass. In a second example, the base to be treated is coated with the acid solution and rubbed with a block or pencil of zinc. A third example utilizes for applying the zinc a solution made up of water, glycerol, sodium nitrite, sodium pyrophosphate, bentonite, methanol and powdered zinc in stated proportions. After this solution has been sprayed on the glass base, a concentrated aqueous hydrochloric acid is applied to wet thoroughly the zinc-coated surface. After an interval of 5 to 10 minutes a water wash removes the tin oxide coating. Where it is desired to effect only partial removal of the tin oxide coating, for example, to produce strips or dots of tin oxide, the glass sheet or other base to be treated is in these areas pre-coated with acidresistant material. Tin oxide coatings may be decreased in thickness by washing the treated surface with water before complete decomposition has occurred. The invention is particularly concerned with heated windshields. Specification 724,086 is referred to.

Title: Silica brick and method of making same
Inventor: VEALE JOHN HEAGY
IPC: C04B33/13
Filed: 1957-04-05
Abstract: Burned and unburned bricks are made by mixing granular silica in an amount of at least 90 per cent. by weight of the total mix with lime, sulphuric acid and a member of the group consisting of phosphoric acid, monobasic calcium phosphate and dibasic calcium phosphate, the amount of sulphuric acid being in excess of that required to form CaSO4 and the calcium being present in not substantially greater amount than that required to combine with the phosphate-containing substance to convert it to tricalcium phosphate, pressing the mixture into shape and drying at a temperature up to about 700 DEG F.  The burned brick is made by further heating the unburned brick thus dried to a temperature of from 2400 DEG F. to 2700 DEG F., the brick then consisting essentially of silica bonded together with tricalcium phosphate.  Suitable burned bricks contain 90-98 per cent. SiO2, 1-7 per cent Ca3(PO4)2, and 0-1 per cent. Al2O3, any Ca2PzO7 present being in minor amount compared with the Ca3(PO4)2.  The silica employed for the production of the bricks may be a granular naturally-occurring form of silica such as ganister or diatomaceous earth, or may be previously converted into tridymite or crystobalite, the majority of the particles not passing a 50 mesh screen.  Examples I to III and V describe the preparation of unburned bricks while Example IV describes the preparation of burned bricks.
